Nail gun, also known as nail shooter, is often called nail gun because of its similar appearance and principle to pistol. It is a fastening tool for driving nails into buildings with blank ammunition, gas or compressed air as power.
Nail gun is an advanced modern nail fastening technology.
Compared with traditional methods such as embedded fixing, drilling and grouting, bolt connection and welding, it has many advantages: it has its own energy source, thus getting rid of the burden of wires and air pipes and facilitating on-site and aerial work; The operation speed is fast and the construction period is short, which can greatly reduce the labor intensity of workers; The function is reliable and safe, and it can even solve some construction problems in the past; Save money and reduce construction cost.
Extended data:
According to the action principle, nail gun can be divided into two categories: direct action nail gun and indirect action nail gun.
Direct-acting nail shooter uses gunpowder gas to directly act on nails to push them to move. Therefore, when the nail gun flies away from the nail tube, the speed (about 500 m/s) and kinetic energy are very high.
The gunpowder gas indirectly acting on the nail shooter does not directly act on the nail shooter, but acts on the piston in the nail shooter, and the energy is transferred to the nail shooter through the piston. Therefore, the nail leaves the nail tube at a lower speed.
